Orthography
German is written in the Latin alphabet. In addition to the 26 standard letters, German has three vowels with Umlaut, namely ä, ö and ü, as well as the Eszett or scharfes s (sharp s), ß.
Written texts in German are easily recognisable as such by distinguishing features such as umlauts and certain orthographical features—German is the only major language that capitalizes all nouns—and the frequent occurrence of long compounds (the longest German word is made of 79 characters).
